. UNITED STATES PATENT OFFIC JOHN ASHBURY LAUGHERY, OF DENISON,MISSOURI.

CHURN.

SPECIFICATION forming part of Letters Patent No. 357,013, dated February1, 1857.

Application filed duly 17, 1886.

Serial in. 203,260. (No model).

To all whom it may concern:

Be it known that I, J OHN AsHBURY LAUGH- ERY, a citizen of the UnitedStates, and a resident of Denison, in the county of Barton and State ofMissouri, have invented certain new and useful Improvements in Ghurns;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference-being hadto theaccompanying drawings, which form a part of this specification,

and in which churns in which a boxlor churn-body is sus-- pended in aswinging frame, and in which a stationary dasher is suspended within thebox or body; and it consists in'the improved con struction andcombination of parts of such a churn, as hereinafter more fullydescribed-and claimed. 7

In the accompanying drawings, the letter A indicates a rectangularupright frame supported upon a suitable base, B, and the side pieces ofthis frame are provided with horizontal cross-pieces O (J, from the endsof which are suspended a pair of pivoted arms, D D,while a pair ofhandles, E E, connected at their upper ends by a handle-bar, F, arepivoted at or near their middles upon the other ends of the crosspieces,the portions of the handles'below their pivotal points being of the samelength as the pivoted arms. A swinging platform, G, is

supported from these arms and handles, having the lower ends of the samepivoted to .its sides near the corners, and the box or body H of thechurn rests upon this platform.

The box has outwardly-inclined end pieces, and the bottom of the box isprovided with transverse cleatsI I at its ends, which cleats bearagainst the ends of the platform, retain-' ing the box upon theplatform, and the top of the box is covered by a cover, J. This cover isformed with two frame -pieces, K K, or braces, which support a long box,L, secured over a longitudinal slot in the cover, and the 5 I upper openend of this long box is Provided wit-h grooved ways M M, or guides, inwhich a plate, N, slides. This plate or slideis formed with aperforation, O, at its middle, and the staff 1? of the dasher Q fits inthis aperture or perforation, the upper end of the staff being securedby means ofa pivoted latch-bar, R, in a recess, S, in one side of thetop cross piece of the frame.

The dasher is perforated, and is of nearly the same dimensions as thecross-section of the interior of the box, nearlyfilling the spacebetween the sides and top and bottom.

The slide in the cover is longer than the box and slot, so that theslide may be slid to both sides, bringing the aperture in it to bothends of the slot and box and still allowing the slot and box to becovered.

When the box has been filled with cream, it is placed upon the swingingplatform, and the cover is placed upon the box, with the dasherstaffprojecting through the aperture of the slide, which is in position inits ways. The upper end of the dasher-staff is thereupon secured by itslatch, and the swinging platform and the box may now be reciprocated,causing the cream containedwithin the box to be forced through theperforations of the dasher, and thus breaking the butter-globules, thepassage through the perforations, together with the swinging motion ofthe body, which causes the cream to swash or wave in the box, causing arapid breaking of the globules and consequent formation of the butter.

The cover is preferably provided with a suit- 0 able aperture, T,through which a thermometer may be inserted, and through which thecondition of the cream and its temperature may be observed. The inclinedends of the boxallow/the swinging box and platform to be so reciprocatedthat the dasher will reach to both ends of the box, and the slide beingsufficiently long will cover the slot and open side of the box upon thecover when the box and plat form are at both extremities of theirstroke.

The churn is very simple of construction,and may consequently be made ofvery strong material, causing it to be durable and not liable to get outof order, and as all parts of the churn which come in contact with thecream may be made of wood there is no danger of tainting the cream orthe butter with any metallic tastes.

Having thus described myinvention, I claim and desire to secure byLetters Patent ofthe United States In a churn, the combination of arectangular upright frame having cross-bars near the upper ends of theside pieces, a pair of arms pivoted at the ends of the cross-bars, apair of handles fulcrumed upon the ends of the crosspieces and connectedat the upper ends by a handle bar, a platform suspended from the lowerends of the arms and the handles, a churn-box upon the platform. a coverupon the box having a longitudinal slot provided with a box at its edgeshaving grooved ways JOHN ASHBURY LAUGHERY.
